摘要：

In this paper, the Wilson nonconforming finite element is considered for solvinga class of second-order elliptic boundary value problems. Based on an asymptoticerror expansion for the Wilson finite element, the global superconvergences, thelocal superconvergences and the defect correction schemes are presented.
